VICKERS威格士柱塞泵美国进口现货 VICKERS威格士柱塞 径向柱塞泵泵分类及工作原理可分为阀配流与轴配流两大类。阀配流径向柱塞泵存在故障率高、效率低等缺点。上70、80年代发展的轴配流径向柱塞泵克服了阀配流径向柱塞泵的不足。由于径向泵结构上的特点,陕定了轴配流径向柱塞泵比轴向柱塞泵耐冲击、寿命长、控制精度高。变量行程短泵的变量是在变量柱塞和限位柱塞作用下,改变定子的偏心距实现的,而定于的zui大偏心距为5—9mm(根据排量大小不同),变量行程很短。且变量机构设计为高压操纵,由控制阀进行控制。故该泵的响应速度快。径向结构设计克服了如轴向柱塞泵滑靴偏磨的问题。使其抗冲击能力大幅度提高。 轴向柱塞泵是活塞或柱塞的往复运动方向与缸体中心轴平行的柱塞泵。轴向柱塞泵是利用与传动轴平行的柱塞在柱塞孔内往复运动所产生的容积变化来进行工作的。由于柱塞和柱塞孔都是圆形零件,加工时可以达到很高的精度配合,因此容积效率高,运转平稳,流量均匀性好,噪声低,工作压力高等优点,但对液压油的污染较敏感,结构较复杂,造价较高。 美国威格士vickers轴向柱塞泵一般都由缸体、配油盘、柱塞和斜盘等主要零件组成。缸体内有多个柱塞,柱塞是轴向排列的,即柱塞的中心线平行于传动轴的轴线,因此称它为轴向柱塞泵。但它又不同于往复式柱塞泵,因为它的柱塞不仅在泵缸内做往复运动,而且柱塞和泵缸与斜盘相对有旋转运动。柱塞以一球形端头与斜盘接触。在配油盘上有高低压月形沟槽,它们彼此由隔墙隔开,保证一定的密封性,它们分别与泵的进油口和出油口连通。斜盘的轴线与缸体轴线之间有一倾斜角度。 美国威格士vickers柱塞泵是液压系统的一个重要装置。它依靠柱塞在缸体中往复运动,使密封工作容腔的容积发生变化来实现吸油、压油。柱塞泵具有额定压力高、结构紧凑、效率高和流量调节方便等优点,被广泛应用于高压、大流量和流量需要调节的场合,诸如液压机、工程机械和船舶中。柱塞泵是往复泵的一种,属于体积泵,其柱塞靠泵轴的偏心转动驱动,往复运动,其吸入和排出阀都是单向阀。当柱塞外拉时,工作室内压力降低,出口阀关闭,低于进口压力时,进口阀打开,液体进入;柱塞内推时,工作室压力升高,进口阀关闭,高于出口压力时,出口阀打开,液体排出。当传动轴带动缸体旋转时,斜盘将柱塞从缸体中拉出或推回,完成吸排油过程。柱塞与缸孔组成的工作容腔中的油液通过配油盘分别与泵的吸、排油腔相通。变量机构用来改变斜盘的倾角,通过调节斜盘的倾角可改变泵的排量。 威格士轴向柱塞泵是利用与传动轴平行的柱塞在柱塞孔内往复运动所产生的容积变化来进行工作的。由于柱塞和柱塞孔都是圆形零件,加工时可以达到很高的精度配合,因此容积效率高,运转平稳,流量均匀性好,噪声低,工作压力高等优点,但对液压油的污染较敏感,结构较复杂,造价较高。柱塞和柱塞套是一对精密偶件,经配对研磨后不能互换,要求有高的精度和光洁度和好的耐磨性,其径向间隙为0.002~0.003mm 威格士vickers柱塞泵头部圆柱面上切有斜槽,并通过径向孔、轴向孔与顶部相通,其目的是改变循环供油量;柱塞套上制有进、回油孔,均与泵上体内低压油腔相通,柱塞套装入泵上体后,应用定位螺钉定位。柱塞头部斜槽的位置不同,改变供油量的方法也不同。 出油阀和出油阀座也是一对精密偶件,配对研磨后不能互换,其配合间隙为0.01mm 。 出油阀是一个单向阀,在弹簧压力作用下,阀上部圆锥面与阀座严密配合,其作用是在停供时,将高压油管与柱塞上端空腔隔绝,防止高压油管内的油倒流入喷油泵内。出油阀的下部呈十字断面,既能导向,又能通过柴油。出油阀的锥面下有一个小的圆柱面,称为减压环带,其作用是在供油终了时,使高压油管内的油压迅速下降,避免喷孔处产生滴油现象。当环带落入阀座内时则使上方容积很快增大,压力迅速减小,停喷迅速。柱塞头部圆柱面上切有斜槽,并通过径向孔、轴向孔与顶部相通,其目的是改变循环供油量;柱塞套上制有进、回油孔,均与泵上体内低压油腔相通,柱塞套装入泵上体后,应用定位螺钉定位。 柱塞头部斜槽的位置不同,改变供油量的方法也不同。出油阀是一个单向阀,在弹簧压力作用下,阀上部圆锥面与阀座严密配合,其作用是在停供时,将高压油管与柱塞上端空腔隔绝,防止高压油管内的油倒流入喷油泵内。出油阀的下部呈十字断面,既能导向,又能通过柴油。出油阀的锥面下有一个小的圆柱面,称为减压环带,其作用是在供油终了时,使高压油管内的油压迅速下降,避免喷孔处产生滴油现象。当环带落入阀座内时则使上方容积很快增大,压力迅速减小,停喷迅速。 VICKERS威格士柱塞泵美国进口现货 PVH074R01AA10A25000000100100010A PVH74C-RF-1S-10-C25-31 PVH074R01AA10B25200000100100010A PVH74C-RF-1S-10-C25V-31 PVH074R01AA10A250000001001AA010A PVH74C-RF-1S-11-C25-31 PVH074R01AA10B252000001001AA010A PVH74C-RF-1S-11-C25V-31 PVH074R02AA10A25000000100100010A PVH74C-RF-2S-10-C25-31 PVH074R02AA10B25200000100100010A PVH74C-RF-2S-10-C25V-31 PVH074R02AA10B252000001001AA010A PVH74C-RF-2S-11-C25V-31 PVH074R01AA10A25000000200100010A PVH74C-RSF-1S-10-C25-31 PVH074R01AA10B25200000200100010A PVH74C-RSF-1S-10-C25V-31 PVH074R01AA10A250000002001AA010A PVH74C-RSF-1S-11-C25-31 PVH074R02AA10A25000000200100010A PVH74C-RSF-2S-10-C25-31 PVH074R02AA10B25200000200100010A PVH74C-RSF-2S-10-C25V-31 PVH074R01AA10A250000001001AB010A PVH74QIC-RF-1S-10-C25-31 PVH074R01AA10B252000001001AB010A PVH74QIC-RF-1S-10-C25V-31 PVH074R01AA10A250000001001AE010A PVH74QIC-RF-1S-11-C25-31 PVH074R01AA10B252000001001AE010A PVH74QIC-RF-1S-11-C25V-31 PVH074R02AA10A250000001001AB010A PVH74QIC-RF-2S-10-C25-31 PVH074R02AA10B252000001001AB010A PVH74QIC-RF-2S-10-C25V-31 PVH074R02AA10A250000001001AE010A PVH74QIC-RF-2S-11-C25-31 PVH074R02AA10B252000001001AE010A PVH74QIC-RF-2S-11-C25V-31 PVH074R01AB10A250000001001AB010A PVH74QIC-RM-1S-10-C25-31 PVH074R02AB10A250000001001AE010A PVH74QIC-RM-2S-11-C25-31 PVH074R01AA10A250000002001AB010A PVH74QIC-RSF-1S-10-C25-31 PVH074R01AA10B252000002001AB010A PVH74QIC-RSF-1S-10-C25V-31 PVH074R01AA10A250000002001AE010A PVH74QIC-RSF-1S-11-C25-31 PVH074R02AA10A250000002001AB010A PVH74QIC-RSF-2S-10-C25-31 PVH074R02AA10A250000002001AE010A PVH74QIC-RSF-2S-11-C25-31 PVH074R01AB10A250000002001AE010A PVH74QIC-RSM-1S-11-C25-31 VICKERS威格士PVH098型号.
